Definitions

  • the present invention relates to a window shield for protective helmets, especially for the users of motor vehicles, whereby the transparent pane of the window shield is detachably connected with the protective helmet.
  • Window shields of transparent plastic material are known in the art which are buttoned onto the protective helmet within the area of their outer circumference.
  • Such a window shield mounted at the protective helmet of a motorcyclist is very easily scratched when wiping off water and dirt from its outer surface, and therewith becomes nearly opaque, from which may result a traffic-endangering visibility impairment of the motorcyclist in case of rain or when driving at night.
  • the entire window shield has to be exchanged in each case after its surface damage.
  • a window shield consisting of a transparent plastic material with a scratch-resistant laminated glass insert.
  • the window shield is thereby equipped in the central area of its field of vision with a circumferential frame, into which the laminated glass is buttoned-in.
  • the disadvantage with this window shield resides in the fact that the laminated glass may break out of the mounting support in case of a force-influence directed against the windowpane, may fall inwardly and therewith may injure the face of the driver.
  • the window shield is made of laminated glass, which extends over the entire field of vision of the window shield, whereby the latter abuts indirectly or directly at the edge area of the window aperture of the protective helmet.
  • the window shield sealingly abuts together with the inner cheek of the mounting support at the outer surface of the protective helmet under interposition of the elastic mounting support which receives both the window shield as also a frame rigidly or pivotally secured at the protective helmet.
  • the mounting support serves, on the one hand, as mounting means of the window shield and on the other hand, as sealing element thereof with respect to the outer surface of the protective helmet, sealing profiles which where heretofore customary for that purpose and were provided at the protective helmet, can be advantageously dispensed with.
  • Another object of the present invention resides in a transparent window for a protective helmet which is not readily scratched when wiping water or dirt off the window.
  • a further object of the present invention resides in a window for protective helmets formed by a transparent window pane which does not endanger the visibility of the motorcyclist.
  • a still further object of the present invention resides in a window shield for protective helmets which minimizes the danger of injury to the face of the driver, while at the same time preserving a relatively large field of vision.
  • FIG. 1 is a side elevational view of a protective helmet with a clear window shield in accordance with the present invention
  • FIG. 2 is a side view of a modified embodiment of a protective helmet with a clear window shield in accordance with the present invention
  • FIG. 3 is a cross-sectional view, on an enlarged scale, taken along line III--III of FIG. 2;
  • FIGS. 4 to 7 are respectively cross-sectional views, on an enlarged scale, through different embodiments of H-shaped cross-sectional profiles of the mounting support illustrated in FIG. 1.
  • a protective helmet 1 illustrated in FIG. 1 is provided with a window aperture 2 which is covered off by a transparent pane forming a window shield and generally designated by reference numeral 3.
  • the window shield 3 is made of laminated glass 6 which extends over the entire field of vision of the window shield 3.
  • the laminated glass 6 is retained by a mounting support 7 of elastic material and abuts within the area of its edge zone under interposition of the mounting support 7 at the edge area of the window aperture 2 of the protective helmet 1.
  • an overlap a results circumferentially between the outer edge of the laminated glass 6 and the circumferential edge of the window aperture 2 so that the window shield 3 cannot reach the interior space of the protective helmet 1 in case of a force-influence directed against the same from the outside.
  • a lining 13 can be seen within the area of the window aperture 2.
  • the elastic mounting support 7 which as such is endless, sealingly abuts with its inner cheek or sidewall 8 at the outer surface of the protective helmet 1 and has an H-shaped crosssectional profile, into the inwardly disposed aperture 9 of which is inserted the laminated glass 6, whereas a frame 11 engages into the outwardly pointing aperture 10, which frame 11 in turn is secured at the protective helmet 1 by means of screws 4 or snap buttons 5.
  • the frame 11 consists of metal or synthetic resinous material.
  • the elastic mounting support generally designated by reference numeral 70 of the window shield 3 illustrated in FIG. 2, includes only an inwardly disposed aperture 90, into which is inserted the laminated glass 6.
  • the elastic mounting support 70 passes over in one piece into the frame generally designated by reference numeral 110.
  • the elastic mounting support 70 and the frame 110 are made as a one-piece synthetic resinous part either by injection molding or suitable casting process, whereby the frame 110 is made appropriately of a harder synthetic plastic material as compared to the mounting support 70.
  • the elastic mounting supports 7 and 70 are provided at their outer sides and in the two lateral areas of the window shield 3 with a number of water-drainage-grooves 12 which extend toward the outside pointing away from the window shield 3. These water-drainage-grooves 12 conduct away the water which collects on the window 3, laterally toward the outside, especially at higher velocities of the motorcycle.
  • the elastic mounting support 70 includes within the area of its inner cheek 8 several outwardly projecting sealing lips 14 which, after fastening of the frame 110 or 11 at the protective helmet 1, abut under prestress at the outer surface thereof and therewith prevent that the water which drains off from the upper and lateral area of the protective helmet 1, is able to enter into the window aperture 2.
  • the elastic mounting support 7 is provided with sealing lips 14.
  • the sealing leg 70' of the elastic mounting support 70 which abuts externally at the window shield 3, includes circumferentially a wedge-shaped cross-sectional profile. It is achieved thereby that within the area of the elastic mounting support 70, on the one hand, the water can drain off readily and, on the other, the surface of the window shield 3 can be easily cleaned.
  • the laminated glass 6 can be equipped with a colored intermediate film 6', by means of which a sun protection advantageously is attainable.
  • FIGS. 4 to 7 illustrate respectively different constructions of the H-shaped cross-sectional profile of the elastic mounting support 7 illustrated in FIG. 1, whereby the two outwardly disposed sealing legs 15 of the elastic mounting support 7, 7a, 7b and 7c have respectively a wedge-shaped cross-sectional profile in their end areas.
  • the H-shaped cross-sectional profile of the elastic mounting support 7 is constructed convexly within the area of the outwardly disposed sealing legs 15.
  • the H-shaped cross-sectional profile 7a is constructed convexly or also ridged within the area of the outwardly disposed sealing legs 15 whereby the outer wall extends undulated merely for purposes of decoration.
  • the H-shaped cross-sectional profile of the elastic mounting support 7b illustrated in FIG. 6 is provided within the area of the outwardly disposed sealing legs 15 with a filler strip 16 which spreads the sealing legs 15 apart in order to attain therewith the safe sealing abutment thereof at the surface of the laminated glass 6.
  • the filler strip 16 may also be provided for purposes of decoration.
  • FIG. 7 illustrates that the H-shaped cross-sectional profile of the elastic mounting support 7c is provided with an undulated inner cheek 8', by means of which a very high sealing effect at the outer surface of the protective helmet 1 can be achieved.
  • the elastic mounting support 7a and 7b is each provided with sealing lips 14 whereas all of the elastic mounting supports 7a, 7b, and 7c are provided with water-drainage-grooves 12.
